    National Park Service U.S. Department of the Interior The Fossil Frontier John Day Fossil Beds National Monument Paleontologists (from left) Furlong, Stock, Merriam, and Chaney Paleontology became popular in the 19th century. Thomas Jefferson told Lewis and Clark to look for living giant sloths in the west. The term ‘paleontology’ was coined in the 1820s to describe the new branch of science dedicated to the study of ancient life. Charles Darwin published On the Origin of the Species in 1859, giving voice to a new idea that plants and animals evolve by way of natural selection in an ever-changing world. A growing awareness for the long age of the earth riveted minds from university halls to street corners. Scientists sought fossils to answer difficult questions about the nature of life.

  • BOOK REVIEWS DON MCCORNACK. (Eugene, Oregon: University of Oregon Press, 1928. Pp. 355. $2.50.)
    BOOK REVIEWS Thomas Condon, Pioneer Geologist of Oregon.. By ELLEN CON­ DON MCCORNACK. (Eugene, Oregon: University of Oregon Press, 1928. Pp. 355. $2.50.) Few recent books on any subject have been freighted with such an abundance of tender sentiment and downright love as has this biography of Thomas Condon, Pioneer Geologist of Ore­ gon. Thomas Condon was "Oregon's Grand Old Man of Sci­ ence." The author of the book is his beloved daughter, his pupil and his legatee. Most of the materials with which Professor Condon worked were as hard as flint but through his long years he was himself as soft as a baby's cheek. Not in any maudlin sense is this ut­ tered for he was a manly man. He was a Christian gentleman and a scientist. In the years of his prime he faced with splendid wurage the then prevailing con:flict between science and religion. His fame as a scholar is secure, not alone in the archives of geology, but in the respect of those who know. As a man he is enshrined in countless memories as a fond and wise parent, as a staunch and helpful friend, as a model citizen, as a loving and loved teacher. Henry Fairfield Osborn, senior Geologist of the United States Geological Survey and President of the American Museum of Natural History, says in the Foreword: "Among these names, bright in the scientific history of America, is that of Thomas Condon. The romantic life of this theist and naturalist stretched across the American continent during the formative period of the sciences of geology and palaeontology and his eighty-four well­ spent years as a high priest of nature qualify him to rank among the immortals." The story of Professor Condon's life-work first appeared in his book, quaintly entitled: Two Islands and What Carne of Them.

  • Dr. Thomas Condon by Unknown This Undated Portrait, Probably Taken in the 1870S, Shows Dr
    Dr. Thomas Condon By Unknown This undated portrait, probably taken in the 1870s, shows Dr. Thomas Condon, one of the most important scientific figures in Oregon history. Thomas Condon was born in County Cork, Ireland, on March 3, 1822. At age eleven he emigrated to New York with his parents. He worked as a school teacher before entering a Presbyterian seminary in Auburn, New York, at the age of twenty-seven. After graduating in 1852, Condon accepted a position as a missionary in the newly settled territory of Oregon. He and his wife Cornelia struggled to make a living in western Oregon before moving to The Dalles in the spring of 1862 to lead the town’s Congregational church. It was in The Dalles where Condon would make his first contributions to the geological sciences. Long interested in natural history, Condon began collecting fossils and giving public lectures on geology soon after moving to The Dalles. In 1865, he accompanied an army patrol from Ft. Dalles into the John Day country, where he had heard there was a rich deposit of fossils. Although he was not the first to discover fossils in the area, he was the first to recognize the significance of the deposit. Condon’s fossil discoveries in the John Day country soon became known to some of the nation’s top paleontologists and geologists, a number of whom—including Othniel C. Marsh, Joseph Leidy, and Edward Drinker Cope—wrote him requesting specimens. Many of the specimens Condon sent were species new to science, and several were named after him.

  • An Abstract of the Thesis Of
    AN ABSTRACT OF THE THESIS OF Shyam Das-Toke for the degree of Master of Science in Geology presented on April 29, 2019 Title: Creating a Predictive Model of Cinder Cone Ages in Central Oregon Abstract approved: ___________________________________________________ Adam J.R. Kent Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. Characterizing large cinder cone fields in terms of age and composition requires significant resources, so this study aims to understand the parameters that influence cinder cone evolution in order to create a predictive age model of cones in Central Oregon. We utilize newly available high- resolution topography and new estimates of cinder cone age to evaluate a quantitative model of cone ages. The field site allows assessment of the effects of cone composition and precipitation in governing the morphology of Central Oregon cinder cones through time. We anticipate that these results will allow estimation of the age of individual cones which have not yet been dated directly. Statistical analyses show that younger cones have both significantly steeper slopes and more defined cone craters than older ones. Results also show that increased local precipitation does not appear to significantly influence cone morphology. However, composition as determined by silica content does influence initial morphology, as weight percentages vary by 15% and lead to differences of 8° in cone slope. After cone formation though, erosive processes such as mass wasting are more influential in influencing cones than chemical content. The statistical model of cone age that we create can be used to estimate cinder cone ages throughout the Central Oregon region and can be used in time-volume studies of monogenetic volcanism.

    The ORE BIN Volume 27, No.1 January, 1965 OREGON'S MINERAL INDUSTRY IN 1964 By Ralph S. Mason* Oregon mines and metallurgical plants continued to pump large quan­ tities of primary wealth into the state's economy in 1964. Indications are that the value produced during the past year wi II probably equal that of the record-shatteri ng total turned in for 1963. Soari ng metal prices on world markets, particularly for mercury, saw the reopening of six cinnabar mines and activity at several antimony properties which have been idle for many years. Production of aggregate, which ac­ counts for approximately two-thirds of the total value of all minerals produced in the state, was close to that of last year, in spite of a lessened demand by large federal construction projects. The disas­ trous Christmas-week floods across the state temporari Iy paralyzed nearly all of the sand and gravel producers, who suffered high Josses to stocks and equipment. The need for aggregate and stone of all types for the coming year will probably set new records as the state rebuilds its highways, jetties, dikes, plants, homes, and bridges. Offshore oi I and gas leases for federal and state lands lying off the Oregon coast were granted to major oi I companies last fall. The action marks an important milestone in the state's long search for petroleum. Metals Mercury A continuing imbalance in the international mercury supply and demand forced prices up to all-time highs in 1964. As a direct result, interest in several Oregon mercury properties developed and at year's end activitywas reported at six mines.

This time period offers a rare chance to observe dramatic climatic changes, such as sudden warming trends. The site is sedimentologically and stratigraphically consistent with the Mascall Formation of the John Day Basin to the north and east of Hawk Rim. Hawk Rim preserves taxa such as canids Cynarctoides acridens and Paratomarctus temerarius, the felid Pseudaelurus skinneri, castorids Anchitheriomys and Monosaulax, tortoises and the remains of both cormorants and owls.
